Compomotive Center Lock Turbo Wheels

[CTR28]

The wheels have be picked up and will be used in a sports racer restoration. Thank you ApexSpeed.


NO SHIPPING. T he wheels must be picked up. They are located in Keizer, Oregon.

Front width: 6”
Front backspace: 2 ½”
Rear width: 8”
Rear backspace: 3”
Center hole dia: 2 ½”*
Pin circle: 3 ¾” *
Pin diameter: 3/8” *

* Measured with a short machinist ruler not a micrometer. The measurements are as accurate as I can get with the ruler but may not be exact.

Front wheels were fitted with 20.0 X 7.0-13” tires. Rear wheels were fitted with 22.0 X 9.0-13” tires.

One front wheel has a dent in the outer ring and will need to be replaced. The inner ring has a small distortion and should be serviceable. The second front wheel has small dent in the inner ring and may/may not be serviceable. The inner and outer rings on the rear wheels have no dents. Replacement rings are available on eBay for less than $100.00.

I know nothing of the history of these wheels. The Lotus EFDA that is on one side of the face of the center section. EFDA is an acronym for European Formula Drivers Association.

If only I was close. Michael,you are very generous to offer these for free!!!

Agree, very generous! I wish I was closer as the 2.5 inch center hole is not very common and what my car uses.
I no its a long shot, do you know anyone coming to Road America for the June sprints or Runoffs this year that could bring them along?
Cheers

Thank you, on the off chance you know someone coming through Oregon I'd be happy to connect and hand them off..

Thank you. That's not likely but as I mentioned to Steve if in the future you happen to know some one passing through Oregon I'd be happy to connect and hand them off.

The wheels are likely to have come from Formula Vauxhall (Opel) Lotus. This was a one-make race series in the late 80's to early 90's to promote GM's European divisions (Vauxhall in the UK and Opel in mainland Europe) along with Lotus, whom GM owned at the time.

The cars were powered by the 2-litre C20XE engine installed in an aluminium monocoque chassis built originally by Reynard in the UK or, later, by Schubel in Germany.

These are great rain wheel sets. Heavy.
The 2.5” hole center on these wheels still typically work with a center lock bolt/fkange nut that is used on a 2.25 hole center. Just less overlap. But check overlap to make sure it’s sufficient.
You could have new center lock flanges machined reasonably.
The drive pins hold wheel in center. Not the flange nut.

You can order new UK spec wheel halves for Compomotives from:
